About this detail

A hollow structural section column is tied into the existing wall construction, enclosed by two layers of 5/8-inch Type X gypsum board on each side to achieve a two-hour fire rating at the door jamb. Continuous backing is provided behind the jambs typically, maintaining an 8 1/2-inch offset to the centerline of steel. Won-door striker jambs are aligned according to the manufacturer specifications, requiring the area between jambs to remain clear from wall bases, applied finishes, and other obstructions.
